1 This invention relates to a device forpositioning a liner in a moldof a type casting machine; Type casting machines'such as the Mergenthaler' linotype are manufactured .with molds having cavities formed by end pieces called linem with the cavity of a certain length, thirty ems or five inches being the most' common length. In setting type for columns of less width it is necessary to change the length of the mold cavity. This may'bedone by taking out one of'ithe regular liners and inserting a longer one. But this operation requires considerable time in unfastening'and refas'tening the mold and in selecting a liner of desired length. Quite often a liner of the exact length required is not immediately available. For convenience the regular liners are termed permanent'liners; An object of this invention is to provide a device for accurately positioning a temporary liner quickly and conveniently in the mold to avoid the inconvenience of interchanging the permanent liners to secure a mold cavity of a particular length. l Means for. accomplishing :this object, together with the method of inserting the temporary liner, will be understood from the following detail description taken in connection with the .accompanying drawing.

- 'Fig. 1 is a quarter turned elevation showing a type casting mold and a device for'inserting a ard mold or a letterhead mold, as Well as the recessed mold, which is shown.

A mold of the character to which this application refers is well known and understood in the art, and a detailed description is unnecessary. Such a mold includes a base I and a cap 2, which are spaced apart by liners 3 and 4 to form a mold cavity 5. In the embodiment as specifically shown, there is a recess or groove 6 in the cap piece 2 so that the face of the type is wider than the stem or butt of the casting. When a liner 4' of minimum length is used the mold cavity 5 is of certain definite standard length, such as thirty ems or five inches.

The liner inserting device which is the subject matter of this application is adapted to 55 position and I insert a short temporary liner I at an intermediate position in the mold cavity 5 to produce a shorter mold cavity of any desired length. As particularly shown, the liner] is three ems in length." It has a straight edge on its, bottom end buthas notches 8 on its upper end.- Thus, when the liner is inserted in the mold, molten, type metal will fill that-portion of the cavity 5 between the liner 4 and the; upper end of the temporary liner 1, and flow into and harden ,in the notches 8 to hold the linersecurelyin position. This leaves an-effective mold cavity between the bottom fof'the liner 1 and the top of'the liner,.3. Solidified'type metal between the liner 4-and thelinerv 1 will remain in the mold while the temporary liner is being used in a particular position. The ejector blade of the type castingmachine will be adjusted to eject a castingpf. the length-provided'by the temporary liner 1 in a particularposition, and will not eject theliner-I or the solidified metal inthe remainingj'portion: of the .mold cavity. Thus, if the liner I is set -:to. produce;a line of fifteen ,ems the ejector blade will be set accordingly. When, however, itis' desired to changethe length of, the mold cavity the ejector; bladeof the machine will be set for the-maximumlength, say thirty ems, and will eject the temporary liner --'l and the cast slugqbetween; the liner 4-;and the'liner I, 'so that the Whole of the cavity 5 will be free. 1 The device which is thesubject matterof this invention is designed to'accurately position, and insertfa; liner 1 injthe cavity 5 at any predetermined'position... m

The device includes j as a support a longitudinal scale piece 19 and a bar l0, rigidly secured to each other by brackets H and I2. The bar l0 serves asa guide for a;follower 1,3, to which is rigidly, securedv a locating finger l4. The finger hason its lowerside a straight, edge. l5 to regisj--. ter with marks on the scale- 9 and adapted to-he inserted into the mold cavity for engagement with the top of the liner or end wall 3 of the mold cavity.

A clamping screw I6 is adapted to clamp the follower Hi to the bar I I] in any selected position. Thus, if it is intended to produce a line fifteen ems in length the follower l3 with the finger I4 is moved along the rod l0 and the scale 7 n for the liner 1 is positioned at the upper end of the scale 9 and the bar l by guides l8. The reciprocating member or carrier IT has a proper cutout or notch to receive the liner 1, as clearly shown in Fig. 3. The inner end of the slide or carrier i! has a lug [9 to engage the end of a guide [8 While the upper end of the slide I! has a lug 20 to engage the other end of the guide l8, thereby limiting the movement of the slide and keeping it from becoming displaced from the support. The carrier I! has an outstanding lug 2| with its inner face flush With the bottom of the groove holding the liner I, which lug engages the face of the mold and accurately positions the liner in the mold cavity depthwise, so that the top of the liner 1 is placed flush with the face of the mold.

The follower l3 has a straight edge 22 which engages the face of the mold and the bracket 12 has aforwardly extending straight edge 23 for engaging the face of the mold, as best shown in Fig.- 2.

" As particularly shown in the drawing, the liner 1 has an outwardly extending flange 24' to. fit in the recess 6. It will be understood, of course, that in a standard mold such a flange will not be present and that in any event a cross section of the liner will correspond with the cross section of the mold cavity of whatever form it may be.

The thickness of the liner 1 should correspond closely to that of the mold cavity so that there will be a nice fit when it is inserted in the cavity between the base I and the cap 2 of the mold.

This fit is such that when the cap 2 is properly tightened in place the liner will be clamped in position.

A description of the method of using the device to insert the liner 1 in the mold cavity is. now

given. Assuming that it is desired to form a mold cavity fifteen ems in length the finger M will be adjusted to the point as shown in the drawing, Figs. 1 and 3, and as explained above. The slide I! will be moved outwardly to the position shown in Fig. 3 and a liner 1 will be inserted in the notch in the slide against the face of the scale piece 9. The device with the liner is placed in the position as shown in Fig. l, with the bottom edge l5 of the finger l4 against the top of the liner 3 and with the edges 22' and 23 against the face of the mold. The outer edge of the slide I1 is pushed to slide the liner 1 into position, the slide ll being stopped when the inner face of the lug 2| strikes the face of the mold. Thus the liner 1 will be accurately placed in position with its outer edge flush with the mold face.

As stated above, the liner 1 is accurately proportioned to nicely fit in the mold cavity. This will necessitate loosening the binding screws, not shown, which hold down the mold cap 2. There are three of these screws for each mold, two engaging the ends 25 of the mold cap respectively and the third engaging the top 26 of the mold cap. Ordinarily it will be necessary to loosen only the center screw, or the one engaging the top 26 of the mold cap. After the liner is inserted as described, the loosened screw or screws may be tightened before the device is taken out of the mold cavity. This is possible because the thickness of the slide ll is less than that of the thinnest portion of the liner 1. An operator may soon become so skilled, however, to the use of the device that he will be able to loosen the cap screw or screws just sufficiently to make a tight fit and the'line'r' I will, upon insertion, fit sufficiently close to stay in position and permit the removat of the positioning device before the cap screws are tightened. As. illustrated in the preferred embodiment, the guides l8. are fixed to the support while the locating finger I4 is movable therealong. While this is a preferred embodimentand advantageous, it may be understood that this condition maybe reversed and that the-finger l4 may be fiized while the guides l8m'ay be arranged on afollower;

It will be obvious that other changes may be made in the details of construction, withinthe scope of the appended. claims, without departing from the spirit. of this invention.

I claim:
